a Chapter 6 contains a complete specification of the referenced standards, which include test procedures, including the reference year version of the test procedure.

b Single-phase, U.S. air-cooled air conditioners less than 65,000 Btu/h are regulated as consumer products by the U.S. Department of Energy Code of Federal Regulations DOE 10 C.F.R. 430 . SEER and SEER2 values for single-phase products are set by the U.S. Department of Energy.

c DOE 10 C.F.R. 430 Subpart B Appendix MI includes the test procedure updates effective 1/1/2023 that will be incorporated in AHRI 210/240-2023.
